Upgrade an economy-class fare on your Delta flight to first-class to enjoy a greater selection of food and beverages than in the main cabin, as well as a more personalized level of service. Upgrade in advance using Delta SkyMiles from your account. Use either SkyMiles or a credit card to purchase an upgrade on the day of your travel if seats in the other cabin are available. Alternatively, if you have SkyMiles elite status, Delta automatically places you on a list for available upgrades the day
